PRINTING ATTACHMENT FOR ROLL-PAPER HOLDERS.

130 it known that we, CHARLEs .l. SULLIVAN and LvsANnEn lllA'lIIEWS, ofSeattle, in the county [T King and State of \Vash ington, have inventedcertain new and useful Improvements in Printing Attachments for Roll-P2per Holders; and we do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable oth- 1o ersskilled in the art to which it appertains to make and use the same.

This invention contemplates certain new and useful improvements inprintingattachments for rollpaper holders.

I5 The object of the invention is to provide a simple andhighly-efficient printing attachment in which the several inking andprinting rolls will be sccurelyheld in position and can be easilyremoved.

A further object is to provide an attachment of this kind which can beapplied to any paper-roll and yet be independent of the paper-rack, savefor the friction between the papera-oll and the printing-roll.

These objects we accomplish by mounting the roll-carrying frame on thebase of the paper-rack, the frame being flexibly supported and providedwith slotted bearings for the journals of the several rolls. Thesejournals are held in their proper positions by pivoted rods which extendoverthe slots in said hearings and in. juxtaposition to the journals.

The invention comprises the novel features of construction and also thedetail combina tion and arrangement of parts, substantially ashereinafter fully set forth, and particu larly pointed out in theclaims.

In the accompanying drawings, Figurcl is a front elevation. Fig. L is anend view. Fig.

4o 3 is a central vertical sectional view looking in the oppositedirection to Fig. 2 and showing a paper-roll. Figs. l and 5 are details.

Referring to the drawings, A designates a frame, which is made of anysuitable material preferably metal, one side of which is open and theother closed. The ends (1 of this frame are parallel. The frame isflexibly supported by two upright arms ',which extend up thereinto andare secured to the 0 ends a thereof. The arms of are connected at theirlower ends to coil-springs (1 which latter are attached by means of armsa to the base-board B of the paper-roll rack. (Not shown.) Thepaper-roll is indicated at I). In practice the arms o, coil-springs aand latoral arms a are all. made of one continuous wire, which is coiledto form the springs and extended outward and bent back upon itself inthe formation of the lateral arms, which latter are united by aconnecting portion 1). In the inner and outer ends of arms are eyes isfor the passage of holding-screws it. Through the coiled springs ispassed a rod U,

to the ends of which are attached holdingplates b. This rod serves tomaintain the proper form of the springs.

C is the printing-roll and J d the inkingrolls, all mounted within frameA. The journals (Pot these rolls tit at their ends in bearings E, whichconsist each of a plate 9, attached to the parallel sides a and havingcentral bulged or flanged portions a, in which are inclined slots e openat their outer ends to permit. of the ii'iscrtion and removal of thejournals. The latter are locked in position 7 in the slots of eachbearing by a rod 1*, which is pivoted at its lower cndf and at its upperend is bent to engage a pin f by which it is held in place, a second pinf against which the rod bears, serving to maintain the same in So atruly straight line. \Vhen the rods 1 are in their normal positions theyare in close juxtaposition to the journals of the several rolls and thuslock the sum 0 in their bearings. It is only necessary to disengage thehooked i ends of the rods from contact with pinsf" and turn themdownward to enable the rolls to be removed. In the curved wall of frameA, on a line with the ink-roll ii, is a longitudinal siot g, throughwhich ink is introduced to the 0 lower ink-roll ll". This slotisnormally closed by a removable cover g".

The tension of the springs of the supporting-arms of the frame serves toconstantly keep the printing or type-carrying roll I) in contact with.the paper-roll. Beyond this and the attachment of the lateral arms a" tothe base-board our attacluncnt is independent of the paper-roll rack.

The ad vantages of our invention are apparout to those skilled in theart to which it appm'tains, and it will be especially observed that thesame is extremely simple and inexpensive and composed of but few parts.llenee it is not liable to readily get out of order. Then, again, it canbe attaehed to any paper-roll raek by simply seeuring the lateral a msto the base-board.

\Ye claim as our invention-- l. A printing attaehment for roll. -paperholders having a frame, inking and printing rolls carried by said frame,supporting arms eonneeted to said frame, springs at the lower ends ofsaid arms, and. lateral arlns extending from said springs, all beingformed from one eont inuons wire substantially as set forth.

2. The combination with the frame and the inking and printing rollscarried thereby, of the two arms attached to the ends of said frame bentat their lower ends to form coilsprings, and extended outwardly to formlateral arms, said supporting arms, springs and lateral arms, all beingformed from one e0n tinuous wire, and the rod fitted in saidcoilsprings, substantially as set forth.

3. In a printing attaehment, a frame hawing j ournal-bea rings at itsends provided with downwardly inel ined slots open at their upper ends,inking and printing rolls having journals titted in said slots, and rodspivoted eaeh at one end and designed to extend over said slots adjacentto said journals, whereby the latter will be held at the inner ends ofsaid slots, substantially as set forth.

r. In a printing attachment, a frame having plates attached to its endsprovided with bulged portions having downwardly int-lined slots open attheir upper ends, inking and printing rolls having journals designed tolit in said slots, pins extending from said plates at or near the upperends thereof, and rods pivotally secured at their lower ends to saidplates and designed to engage said pins, the upper ends of said rodsbeing bent out, said rods being extended over said slots adjacent tosaid jtn'lrnals, substantially as set forth.

In a printing attachment, the eombination with the printing and inkingrolls, of the frame snp nn'ting said rolls and having a slot in rear ofone of said inking rolls, and a removable eover for said slot,substantially as set forth.

ti. The ln*rein-deseribml improved ninting attachment for rollpaperholders, comprising the frame having a slot, a removable eovertherefor, slotted journal bearings at the ends of said frame, inking andllllllll rolls having their journals fitted insaid bearings, pivotedlocking rods for holding said journals in position, supporting armseonneeted to the ends of said frame and formed at their lower ends intocoil springs and lateral arms, and the rod fitted in said eoil springs,substantiall as set forth.

In testimony whereof we have signed this speeifieation in the preseneeof two subset-ibing \s 'itnesses.
